Dilaton Effective Field Theory [PDF]
Universe, 2022 We review and extend recent studies of dilaton effective field theory (dEFT) that provide a framework for the description of the Higgs boson as a composite structure.

Effective Field Theory of Random Quantum Circuits [PDF]
Entropy, 2022 Quantum circuits have been widely used as a platform to simulate generic quantum many-body systems. In particular, random quantum circuits provide a means to probe universal features of many-body quantum chaos and ergodicity.

Effective field theory for hydrodynamics without boosts [PDF]
SciPost Physics, 2021 We formulate the Schwinger-Keldysh effective field theory of hydrodynamics without boost symmetry. This includes a spacetime covariant formulation of classical hydrodynamics without boosts with an additional conserved particle/charge current coupled to ...

DsixTools 2.0: the effective field theory toolkit [PDF]
European Physical Journal C: Particles and Fields, 2021 DsixTools is a Mathematica package for the handling of the standard model effective field theory (SMEFT) and the low-energy effective field theory (LEFT) with operators up to dimension six, both at the algebraic and numerical level.

The geometric Standard Model Effective Field Theory [PDF]
Journal of High Energy Physics, 2020 We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the 2 H † H / Λ $$ \sqrt{2\left\langle {H}^{\dagger }H\right\rangle }/\Lambda $$ expansion relevant for studies

ALPs effective field theory and collider signatures [PDF]
European Physical Journal C: Particles and Fields, 2017 We study the leading effective interactions between the Standard Model fields and a generic singlet CP-odd (pseudo-) Goldstone boson. Two possible frameworks for electroweak symmetry breaking are considered: linear and non-linear.

The standard model effective field theory at work [PDF]
Reviews of Modern Physics, 2023 The striking success of the Standard Model in explaining precision data and, at the same time, its lack of explanations for various fundamental phenomena, such as dark matter or the baryon asymmetry of the universe, suggests new physics at an energy ...

Radiation-reaction in the Effective Field Theory approach to Post-Minkowskian dynamics [PDF]
Journal of High Energy Physics, 2022 We extend the Post-Minkowskian (PM) effective field theory (EFT) approach to incorporate conservative and dissipative radiation-reaction effects in a unified framework.

Consistency of effective field theory analyses of the BOSS power spectrum [PDF]
Physical Review D, 2022 We assess the robustness of $\Lambda$CDM results from the full-shape analysis of BOSS power spectrum using the one-loop prediction of the Effective Field Theory of Large-Scale Structure (EFTofLSS).

Gravitational effective field theory islands, low-spin dominance, and the four-graviton amplitude [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 We analyze constraints from perturbative unitarity and crossing on the leading contributions of higher-dimension operators to the four-graviton amplitude in four spacetime dimensions, including constraints that follow from distinct helicity ...
